## Job description

Join Proton and build a better internet where privacy is the default

At Proton, we believe that privacy is a fundamental human right and the cornerstone of democracy. Since our inception in 2014, founded by a team of scientists from CERN, we have dedicated ourselves to providing free and open-source technology to millions worldwide, ensuring access to privacy, security, and freedom online.

Our journey began with Proton Mail, the largest secure email service globally, and has since expanded to include Proton VPN, Proton Calendar, Proton Drive, and Proton Pass. These tools empower individuals and organizations to take control of their personal data, break away from Big Tech’s invasive practices, and defeat censorship. Our work impacts hundreds of millions of lives, from activists on the front lines defending freedom to leaders in governments protecting sensitive information. In some cases, Proton’s services have even been instrumental in saving lives by enabling secure and private communications in high-risk situations.

Proton is a profitable company that does not rely upon VC funding, supporting over 100 million user accounts with a growing team of over 500 people from over 50 different countries, from the world's top companies and universities. We value intelligence, learning potential, and ambition in our hiring process. Adaptability is key as we navigate uncharted territories and redefine how business is conducted online.

Hiring at Proton is highly selective, with less than 1% of candidates hired. We believe smaller teams of exceptional talent will always prevail over larger teams with lower talent density. You will have the opportunity to work with many of the world's top minds in their fields, ranging from former international math and science olympiad winners to chess champions.

We have a global mindset and big ambitions but remain a start-up at heart. We value empowerment and flexibility and keep our structure flat to keep moving fast and avoid unnecessary politics. Tired of blending into the crowd? Join us and do work you can truly be proud of. Check our open-source projects [here](https://proton.me/community/open-source)!

The Team

As a Front-end Engineer at Standard Notes, you will play a crucial role in evolving our platform into the leading secure note-taking, knowledge management, and productivity solution. We are seeking a senior engineer who is passionate about client-side architecture, system design, and usability, and who thrives in a highly collaborative environment. You’ll work closely with Product, Design, API teams, and fellow engineers, driving data-informed decisions to deliver a seamless and secure user experience.

Current Projects:

The Standard Notes team is focused on building a comprehensive suite of tools to help users manage their knowledge and boost productivity while maintaining the highest standards of security and privacy. Recent efforts include advancing editor capabilities, improving data organization features, and optimizing cross-platform sync. You’ll work on architecting features such as encrypted search, tagging systems, advanced note formatting, and seamless integrations—all built with React and TypeScript and secured with end-to-end encryption.

Tech Stack and Tools:

- JavaScript, TypeScript, React, ES6, Playwright, Jest, Grafana
- All Standard Notes codebases are open source: https://github.com/standardnotes

Encryption presents unique challenges to front-end development. Features like search and syncing are designed to function entirely within a secure and encrypted environment, pushing the boundaries of what’s possible in privacy-first software.

Future Plans:

As a team, we aim to continuously enhance the quality and performance of Standard Notes, transforming it into a feature-rich platform that caters to the diverse needs of both individuals and businesses. This includes improving knowledge management capabilities, expanding organizational tools, and creating integrations that enhance workflows—all while remaining committed to our core values of security, privacy, and simplicity.

What You Will Do:

- Develop, deploy, and support high-quality user experiences across our product portfolio, including features that enhance knowledge management, productivity, and data organization.
- Transform product specifications into technical requirements and lead your team to their successful implementation.
- Enhance Standard Notes’ development lifecycle, tools, and code structure for an improved developer experience through technical leadership and architecture.
- Write clear, concise, and testable code to maintain and elevate the quality of our codebase.
- Scope, plan, and execute new features, technical initiatives, and greenfield projects (depending on seniority).
- Foster a culture of learning, creativity, and accountability for the best possible work through mentorship and team development, role modeling quality assurance, and performance optimization.

Job Requirements:

- Deep understanding of JavaScript methodologies and design patterns
- Proficiency with TypeScript or any typed language
- Experience with React or 2+ similar frameworks, developing performant and reusable components
- Strong understanding of software engineering best practices, such as SOLID, Design Patterns, CI/CD
- A product mindset with a focus on offering the best user experiences
- Experience working in a distributed team

Bonus points for:

- Awareness of common security issues in client-side development, such as those in the OWASP top ten, and how to mitigate them
- Familiarity with UX, accessibility, internationalization, and localization concerns and solutions
- Experience with Grafana or other monitoring platforms
- Experience with breaking down product requirements into architecture design and implementation
- Experience with NodeJS
- High-level understanding of cryptography concepts such as key exchange and the difference between symmetric and asymmetric encryption

What We Offer:

- Office First: Collaboration is easier and more effective in person, which is why we have offices in Geneva, Zurich, Prague, Barcelona, Paris, London, Vilnius, Skopje, and Taipei. You can also enjoy working from home up to 30% of the time, while enjoying great company during our three core days in the office.
- Technology: We provide all the devices and software you need to excel in your role, ensuring you have the best tools at your disposal to achieve your goals.
- Food: Lunch and snacks are provided by Proton every day at our offices.
- Transport: We will always support our employees with transport costs through subsidizing public transport, bike allowances, or parking spaces based on your office location.
- Stock Options: At Proton, we are all owners of the company and you get stock options when you join us.
- Flexible Working: You can define your own working hours as long as it works with team meetings.
- Learning and Development: We are committed to your professional growth. Proton offers various learning opportunities, including training programs, conferences and events, and continual learning.
- Employee Benefits: Comprehensive health insurance plans, competitive retirement savings options, generous vacation and leave policies, and wellness programs.
- Work that Matters: Proton is a community-first organization, started with the support of a crowdfunding campaign and built with community input. To this day, Proton’s only source of revenue is user subscriptions. Over 100 million people trust and support Proton, and we put our users and community first in everything we do.
